Opening Day 2026 is fast approaching, but before we get there, I have one more major offseason piece to publish: my annual Future Hall of Fame Series! It feels like the last few editions have all been special occasions that beget nostalgia, like anniversaries or major milestones, but this year in contrast looks rather quaint in comparison; this entry isn’t a round number, and while one of this year’s two BBWAA inductees was once again a former inclusion in this series, it was Carlos Beltran, who already had a pretty solid case and was nearing the end of his career by the time he was featured here. There are still a few more guys on the ballot who retired too early for me to cover them here, but that number continues to drop every year. I’ll cover that when we get there, though. For now, let’s dive right in!
​
​(Note: Once again, this piece got rather long, so I’ll be splitting it up into multiple parts, with the second half to follow next week. Be sure to check back for that!)​

​The Methodology​
Before we start going over the players, let me give a quick explanation for how my system works. It’s a bit of a multi-step process.
​
First, I find the Median Hall of Fame Pace, to help give an idea of what a sort of generalized Hall of Fame hitter’s career “could” look like. That’s easy enough, just going through Baseball-Reference’s Stathead search, looking at every Hall of Fame position player, going age by age, and looking for the exact midpoint to find the median Wins Above Replacement for that age-season.* So, to use fake numbers for an example: if there were 25 Hall of Famers, we’d be looking for the WAR total of the 13th one, right in the middle, at age 23, then 24, then 25, and so on. Simple enough. These are the Medians that we’ll be comparing active players too; if a modern player is above that total, they have more WAR than half of the Hall of Famers did at the same age.
​
​*Side note: since part of this series is to be predictive, I limit my numbers to just AL and NL stats, since it’s the most similar to the game today. Also, I only look for the median of Hall members who were active through that age, so anyone who debuted at, say, 23 isn’t included in the age 22 pool.​
​
Second, we find the rough Hall of Fame chances for players above that Median at every age. To do that, I look at how many players in history have attained that median WAR total by that age. Then, I just compare that to the number of Hall of Famers. So, going back to our fake numbers, if there are 12 Hall of Famers above the Age 23 median, and 8 unelected players in history were above that total too, then we have (12 Hall of Famers) divided by (12 Hall members plus 8 non-Hall, or 20 total), giving us a 60% chance of players ahead of the Hall of Fame pace at that age actually going on to Cooperstown.
